countyof, Bristol and State of Rhode Island,

have invented a new and useful Improvement in Top-Roll Saddles, of whichthe following is a specification.

This invention has reference to an improvement in top roll saddles andmore particularly to an improvement in the means for oiling the bearingsof the saddles.

Top roll saddles as heretofore constructed require to. be oiledfrequently, and when oiled by the operator are usually given an amountof oil in excess of what the wicks in the saddles can hold, the excessof oil running off the saddle being wasted. In practice I find that theloss in time required to frequently oil the saddles and the waste of oilin excessively oiling the saddles are considerable. the oil used inlubricating top roll saddles will creep up the sides of a metallic bodyto quite a height and therefore utilize this fact in the construction ofmy saddle.

The object of my invention is to improve the construction of top rollsaddles whereby the bearings of the saddles are oiled for a longer timewith one oiling and with less Waste of the oil in oiling than hasheretofore been done.

My invention consists in the peculiar and novel construction oftop rollsaddles, said saddles having longitudinal grooves connecting with holesleading to the saddle bearings, oil wicks in the grooves and holes, andan oil well intersecting the groove and adapted to feed oil to the wickby capillary attraction, as will be more fully set forth hereinafter.

Figure 1 is a side view of the front and back top roll saddles, showingthe saddles bearing on. the journals of the top rolls, and the oil Wellsin the saddles intersecting the longitudinal grooves in broken lines.Fig. 2 is an enlarged top plan view of the front top roll saddle,showing the oil well intersecting the longitudinal groove in which isthe oil wick. Fig. 3 is a sectional view taken lengthwise through thefront top'roll saddle, showing the construction of the oil well. Fig. 4is an enlarged top plan view of the back top roll saddle, and Fig. 5 isa sectional view taken lengthwise through the back saddle.

I also find in practice that.

In the drawings, a a indicatethe journals of the top rolls, b the backsaddle, c the front saddle, d d the oil Wells in the front and backsaddle, e e the oil wicks, and f the weight strap. The back saddle b isc'onstructedto form the bearings b b for the backjand intermediate toproll journals, the longitudinal groove b intersecting the oil well (1,the holes 12 b leading from the ends of the groove 1) to the bearings bb and to support the rear end of the front saddle c. The forward end ofthe front saddle c is constructed to have the bearing 0 for the journalof the front top roll, the longitudinal groove 0 intersecting the oilwell (i and the holes 0 0 leading from the ends of the groove 0 to thebearing 0, otherwise the front and back saddles may have theconstruction of any of the well-known forms of top roll saddles. The oilwicks e e extend across the open tops of the oil wells (1 din thelongitudinal grooves b and c and then downwards throu h the holes 12 band'c c to the bearings of the saddles, as shown in Figs. 3 and 5.

In the use of my improved top roll saddles the wicks e e are oiled bythe o erator in the usual way, the excess of oil col ecting in the oilwells d d from which it is fed to the wicks by capillary attraction,when required. If from unusual causes heat is generated in the bearingsof the saddles, it materially assists the capillary attraction of theoil in the oil Wells.

By the use of my improved top roll'saddles, the bearings of the saddlesare oiled for a greater period with one oiling and a more perfect oilingaction is maintained on the bearings than has heretofore been done.

It is evidentthat the capillary attraction of the oil in the oil wellscould be assisted if desired by filling the oil wells with an absorbentmaterial without materially affecting the spirit of my invention.

Having thus described my invention, I claim as new'and desire to secureby Letters Patent 1. In a top roll saddle, having a groove and holesconnecting the groove with the bearings of the saddle, an oil wellintersected by the groove, and an oil wick extending across the top ofthe oil well, as and for the purpose described.

2. In a top roll saddle, a groove, an oil wick in the groove extendingacross the top of the oil well, and an oil well intersected by thegroove and from which oil is fed to the wick by capillary attraction, asdescribed.

3. A'top roll saddle formed with a groove and vertical holes, an oilwick in the groove and holes, the oil wick extending across the top ofthe oil well, and a recess forming an oil well intersected by the grooveand from which oil is fed to the wick by capillary attraction asdescribed.

4. A'top roll saddle having bearings, a groove above the bearings, holesconnecting the groove with the bearings, an oil wick extending acrossthe top of the oil well in the groove and holes, and a circular recessforming an oil Well intersected by the groove, and from which oil is fedto the wick in the groove by capillary attraction, as described.

5. A back top roll saddle, having the bearings b b, the groove, theholes 5 6 a circular recess forming the oil well d intersected at thetop by the groove, and the oil wick e in the groove and holes, asdescribed.

6. A front top roll saddle, having the bearing a, the groove 0 the holes0 0 a circular recess forming the oil well d intersected by the groove,and the oil wick e in the groove and holes, as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
